Bells and associated mechanisms require appropriate ongoing maintenance to keep them safe and working effectively. The more routine elements of such work are classed as Minor Works not requiring application for a faculty (full details are set out in the Minor Works guidance) but all significant work will have to go through the full faculty process.
Bell-ringing activity needs to be managed so that it does not cause undue disturbance to local communities. Useful practical guidance on this is available in the document Church Bells and the Law. Detailed advice: The Diocesan Bells Adviser is available to provide advice on particular schemes - please contact the DAC Secretary in the first instance. The Church Buildings Council has produced a code of practice on The Conservation and Repair of Bells and Bell Frames which sets out the technical aspects in very great detail.
The Central Council of Church Bell Ringers has some very worthwhile advice for PCCs on the issue of telecoms installations. There are significant wider issues that PCCs also need to consider (practical, structural, ethical and legal) and they should contact the DAC Office for detailed advice at an early stage.
